President Trump paused his White House meeting with European leaders Monday afternoon, saying he was going to call Russian President Vladimir Putin, according to two senior European officials at the meeting.

Ukrainian President Volodymyr Zelensky indicated that he would like to see President Trump participate in a future meeting with Russian leader Vladimir Putin, should such a face-to-face come to fruition.

The Ukrainian president says Monday's talks have been "constructive" as European leaders repeat calls for a ceasefire.
